Honestly, I love them all! NoahSamuel and HenryDaniel are my favorites, although I think Amelie and William would be lovely together, and Philip is very respectable and handsome--just not to my taste, really.

I think Amelie and Henry work a bit better together, so that would get my vote, but I adore Noah, too. I think Amelie and Samuel would be fab for siblings, too, for what it's worth. SamuelHenry would be swoonworthy.

HenryDaniel is definitely my favorite of the four, by quite a wide margin. It's a very strong sounding name. WilliamElliot would be my second favorite, though it is a bit 'l' heavy. Noah and Phillip I'm not the biggest fan of, but they're certainly fine, usable names, not not my personal preferences. I really like the names Edward and Elliot a lot too, think they'd be solid first name options.
